AC/DC converters are devices that convert one form of electrical power into another. They are commonly used to convert alternating current (AC) into direct current (DC). The ML60.242 converter is a medium-powered, high frequency AC/DC converter which provides a large output voltage range for a wide variety of applications. This article will discuss the application field and working principle of the ML60.242 converter.

Application Field of ML60.242
The ML60.242 converter is specifically designed to provide medical safety isolation in devices such as digital safety analyzers and monitors. It is capable of providing isolation of up to 4000 Vrms for very high voltages and up to 200 mA of output current. This converter is also suitable for use in various industrial and military applications, such as air-to-ground communication equipment, satellite dishes, and defense applications.

In addition, the ML60.242 converter is a high frequency, high power AC/DC converter ideal for applications requiring a wide output voltage range. It is capable of providing output voltages ranging between 110 to 540 Vrms at frequencies up to 800 kHz. This feature makes it perfect for use in a variety of AC/DC power conversion applications, including AC/DC power sources, servo motor drives, and UPS systems.

Working Principle of ML60.242
At the heart of the ML60.242 converter is a special silicon-on-insulator (SOI) HV technology which features a low EMI profile and high isolation of up to 4kVrms. The converter is comprised of 4 identical half bridge circuits. Each circuit includes two bipolar MOSFETs connected in anti-parallel to create a full bridge. The gate capacitances of the FETs are reduced to avoid the bottleneck in high frequency switching applications.

The ML60.242 is a closed-loop, current-mode converter. It features a fixed frequency, current-mode PWM control scheme. This control technique allows the converter to provide a very high accuracy of the output voltage. Furthermore, the ML60.242 is capable of providing a wide dynamic range with variable output voltage. Additionally, the converter features constant on-time PWM control with adaptive dead-time that provides fast transient response and high efficiency.

The ML60.242 features a safe operating area (SOA) protection system. The SOA monitoring circuit will detect an over current or over voltage condition and will shut off the converter if an unsafe condition is detected. This feature helps to protect the device from short circuits or over voltage fault conditions.

In addition, the ML60.242 can be operated in both continuous conduction mode (CCM) or discontinuous conduction mode (DCM). The converter optimizes efficiency in all modes while providing a low EMI noise profile.

The ML60.242 converter is a very reliable and easy to use AC/DC converter. It provides a wide output voltage range and is capable of providing very high isolation of up to 4kVrms. The converter is designed to meet the requirements of various medical, industrial, and military applications. Furthermore, the SOA protection system provides a safe working environment while the current-mode PWM control ensures high efficiency and fast transient response.
